Rhodesain, the major cathepsin L-like cysteine protease in the protozoan Trypanosoma brucei rhodesiense, the causative agent of African sleeping sickness, is a well-validated drug target. In this work, we used a fragment-based approach to identify inhibitors of this cysteine protease, and identified inhibitors of T. brucei. To discover inhibitors active against rhodesain and T. brucei, we screened a library of covalent fragments against rhodesain and conducted preliminary SAR studies. We envision that in vitro enzymatic assays will further expand the use of the covalent tethering method, a simple fragment-based drug discovery technique to discover covalent drug leads.

In a article, 19301-35-0, molcular formula is C8H6OS, introducing its new discovery.

Enzymatic cis-dihydroxylation of benzo[b]thiophene, benzo[b]furan and several methyl substituted derivatives was found to occur in both the carbocyclic and heterocyclic rings. Relative and absolute configurations and enantiopurities of the resulting dihydrodiols were determined. Hydrogenation of the alkene bond in carbocyclic cis-dihydrodiols and ring-opening epimerization/reduction reactions of heterocyclic cis/trans-dihydrodiols were also studied. The relatively stable heterocyclic dihydrodiols of benzo[b]thiophene and benzo[b]furan showed a strong preference for the trans configuration in aqueous solutions. The 2,3-dihydrodiol metabolite of benzo[b]thiophene was utilized as a precursor in the chemoenzymatic synthesis of the unstable arene oxide, benzo[b]thiophene 2,3-oxide.

Starting from 1 (MEN 14268), a selective tachykinin NK2 receptor antagonist with an interesting in vitro pharmacological profile, a family of numerous antagonists was obtained through an optimization process focused on iterated structural modifications. The effects of the introduction of a wide variety of substituents on the lipophilic aromatic part of the molecule and the modulation of the structural constraint through the insertion of different achiral alpha,alpha-dialkylamino acids were investigated. In particular, aromatic and benzofused heteroaromatic moieties were introduced at the pseudo-N-terminal residue to replace the 2-benzothiophene moiety, and a systematic investigation of the best positioning of substituents onto the aromatic platform was reported for the benzothiophene core. Studies on the modulation of the length and the rigidity of the hydrophilic pseudo-C-terminal pendant are presented. Many heteroaliphatic groups are well tolerated by the receptor in this part of the ligand. The product 48f (MEN15596), bearing a methyl substituent on the benzothiophene and a tetrahydropyranylmethylpiperidine pendant, was finally selected for its good in vivo activity after intravenous, intraduodenal, and oral administration in guinea pigs.

Raloxifene,[2-(4-hydroxyphenyl)-6-hydroxybenzo[b]thien-3-yl][4-[2-(1- piperidinyl)ethoxy]phenyl]-methanone hydrochloride (2), is representative of a class of compounds known as selective estrogen receptor modulators (SERMs) that possess estrogen agonist-like actions on bone tissues and serum lipids while displaying potent estrogen antagonist properties in the breast and uterus. As part of ongoing SAR studies with raloxifene, we found that replacement of the carbonyl group with oxygen ([6-hydroxy-3-[4-[2-(1- piperidinyl)ethoxy]phenoxy]-2-(4-hydroxyphenyl)]benzo[b]thiophene hydrochloride, 4c) resulted in a substantial (10-fold) increase in estrogen antagonist potency relative to raloxifene in an in vitro estrogen dependent cell proliferation assay (IC50 = 0.05 nM) in which human breast cancer cells (MCF-7) were utilized. In vivo, 4c potently inhibited the uterine proliferative response to exogenous estrogen in immature rats following both sc and oral dosing (ED50 of 0.006 and 0.25 mg/kg, respectively). In ovariectomized aged rats, 4c produced a significant maximal decrease (45%) in total cholesterol at 1.0 mg/kg (po) and showed a protective effect on bone relative to controls with maximal efficacy at 1.0 mg/kg (po). These data identify 4c as a novel SERM with greater potency to antagonize estrogen in uterine tissue and in human mammary cancer cells compared to raloxifene, tamoxifen or ICI-182,780.

Synthetic Route of 4923-87-9, New research progress on 4923-87-9 in 2021. The transformation of simple hydrocarbons into more complex and valuable products via catalytic C–H bond functionalisation has revolutionised modern synthetic chemistry. In a article, 4923-87-9, molcular formula is C8H5BrS, introducing its new discovery.

The first example of near-room-temperature alpha-arylation of benzo[b]thiophenes is reported. The discovery rests on the observation of a switch in alpha-/beta-regioselectivity at different loadings of Pd2(dba)3·CHCl3 in the coupling between benzo[b]thiophene and 4-iodotoluene. We show that this unprecedented regioselectivity switch is driven by a Ag(I)-mediated C-H activation at the alpha-C-H position, which becomes the dominant mode of reactivity at low concentrations of Pd. Competition experiments, kinetic studies, KIE, and D/H scrambling experiments have been carried out supporting this mechanism.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 4923-87-9 is helpful to your research. Synthetic Route of 4923-87-9
